Abstract

This invention discloses a method to reduce the damage to ears when hearing audio in a noisy environment. When the volume is beyond the base healthy volume, the invention will check the audio tracks to see whether one audio track contains important information or not: E.g. in a movie, human speech is more important then background music, in a singing show, the voice of singer is more important than cheer of the audience. It will decrease the volume of less important audio track or even remove the less important audio track to reduce the overall volume. For each audio track, it will also parse the content to see in certain time period, whether the volume should be kept or not.

However, the high volume does harm to people's hearing. There are some available methods to remind people to turn down the volume when they turn up the volume to a value that is beyond human's healthy range. But in real situations, many people would like to continue watching interesting videos and will therefore ignore the reminder. Is there a smarter method to allow people to watch videos, but meanwhile reduce the harmful impacts of the high volume to their hearing?

In this invention, system accepts audio stream of video as input and output the audio after process. There is a volume called "Base volume" in this description part. "Base volume" is the recommended sound volume for human from medical science. Device volume is the volume of the device. Audio/video volume is the volume from video. Once system detects user increase/reduce device volume while watching video, system will start to work. If video volume is below the base volume, system will not do additional work. But if the video volume is above the base volume, system will try to identify the important sound for the specified scene. System identify the scenario by the video content. When the device volume is going up(video volume above th...
